JOHN NUTTALL, OF BRIDGEPOR'I, CONNECTICUT.

STOPPER FOR WATER-BAGS AND THE LIKE.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed February 28, 1905. Serial No. 247821.

To all whom it may concern:

Be it known that 1, JOHN NUT'IALL, a citizen of the United States, residing in Bridgeport, Fairfield county, State of Connecticut, have invented certain new and useful Improvements in Stoppers for Water-Bags and the Like, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings forming part of this specification.

My invention relates to an improved adjustable and non-detachable stopper which is particularly well adapted for use with what is knownas a water bag and which generally comprises a flexible bag of rubber, the same being bottle shaped with the mouth thereof pro- I vided with a tubular metallic body or fitting into which is generally placed an ordinary plug or stopper.

My present invention consists in the various novel and peculiar arrangements and combinations of the several different parts of the device, all as hereinafter fully set forth and then pointed out in the claims.

I have illustrated types of my invention in the accompanying drawings wherein Figure 1 is a vertical central sectional view of my improved non-detachable stopper shown as mounted in the mouth of the bottle, the lower part of which is broken away. Fig. 2 is a side View of the yoke detached. Fig. 3 is a plan view of the yoke detached. Fig. 4 is a side view of the tubular fitting together with the supports for theyoke shown as detached and in position to be united with the yoke above it. Fig. 5 is a plan view of the parts shown in Fig. 4. Fig. 6 is a side view of the thumb-screw shown as detached from the stopper. Fig. 7 is a central vertical sectional view of the stopper, detached. Fig. 8 is a view similar to that shown in Fig. 1, of a modified form of the device. Fig. 9 is a horizontal sectional view of the stopper de vice, detached, the section being taken above the plane of the yoke or support for the thumb-screw. Fig. 10 is a plan view of the tubular fitting of the support for the yoke and having the yoke removed.

Referring to the drawings, in which like numbers of reference designate like parts throughout, 1 is an ordinary flexible water bag or vessel having a mouth 2, in which is secured a tubular-fitting 3, by means of projections or roughened surfaces 4, on the exterior of the tubular-part taking into the material of the bottle or vessel.

The fitting 3 is made of a suitable metal and is formed with an annular-seat 5 for receiving the stopper 6, these two parts being finished to fit each other and a rubber washer 6 is used to make a water-tight joint when the stopper is held on its seat under pressure. The stopper 6 is a somewhat fiat circular body, shaped like a disk, and is formed on its back or upper side with a socket 7, in which fits a ball 8 on the lower end of the thumb-screw 9, the thread 10 of which works in a corresponding screw-thread in an opening 11 in the yoke 12 which is secured between the supports or uprights 13 which extend in fixed position from the tubularfitting 3, and which in the present construction are shown as formed integral therewith and at two opposite points thereon. The respective ends of the yoke which are made fast to the supports 13, by means of small screws 15 passing through holes 16 in the yoke and taking into the supports. This yoke 12 spans the opening in the tubular part 3 and has its center in axialalinement with the tubular part The material of the stopper at 17 is pushed or worked over the ball 8 after the same is entered into the socket 7 so as to retain the ball therein and thus attach the stopper to the thumb screw, the stopper at the same time having a limited motion on its ball-and-socket joint. In making the parts, a surplus of material is left at 17 at the back of the stopper for the purpose of being worked over upon the ball to attach the stopper to the thumbscrew.

In assembling the parts, the thumb screw may first be put through its bearing in the yoke 12 and then the ball entered into the stopper and the joint between the two finished so as to attach the stopper to the thumb-screw. Then the stopper is dropped down between the supports 13 so that it may be closed on the annular seat 5 and the yoke is then united to the supports by means of the screws 15. I

In Figs. 8, 9 and 10, I show a modified form more particularly of the yoke and its mounting on the supports. In this construction, the yoke 18 is in the shape of a cap having a central opening 19 formed with a screw thread so as to afford a bearing for the thumb-screw 20, which is attached to the stopper 6 by means of the ball-and-socket joint, as previously described. The cap or yoke 18 fits over upon a set of uprights or supports 21 extending upwardly from the tubular fitting 3 there being three of these supports indicated with a suitable space between them. The cap 18 is provided with screw holes 22 through which small screws may be entered and passed into the sup-- ports, to screw the parts together. I have shown the thumb-screw as having different style of head or thumb piece and either of the parts may be used as desired.

The device described may be applied to any sort of vessel for holding liquids such as ordinary bottles or what is known as a water bag which in the drawings is indicated at 1, the mouth 2 of which is provided with a fiaring part 23 for readily filling the bag. From the foregoing description it will be seen that the stopper is at all times non-detachable so that it is always retained in place to be readily and quickly applied and this has its advantages over a detachable form of stopper which is apt to get Inislaid or lost. In using the stopper, the. thumb-screw is turned up to open the mouth of the bottle or receptacle and is turned down in order to close it and it can be closed with more or less pressure depending on how hard the screw is turned down. 7

Having thus described my invention what I claim and desire by Letters Patent is 1. The combination of a bag or bottle-like vessel provided with an annular seat 5 secured withinthe mouth thereof and adapted to receive a stopper for closing said vessel, a stopper 6 fitting the said seat and provided on its upper side with a socket 7, a fixed yoke or frame mounted upon said annular part, a thumbscrew 9 having a threaded bearing 11 in said yoke and provided at its lower end with a ball bearing 8 fitting the said socket 7, said thumb-screw being adapted to open and close the stopper on its seat but not to rotate it thereon.

2. The combination of a bag or bottle-like vessel provided with a mouth having a seat adapted to receive a stopper for closing said vessel, a stopper fitting the said seat, a set of projections or supports extending up from said seat, a yoke secured to said supports, and a thumb screw having a threaded bearing in said yoke and connected with said stopper, substantially as and for the purpose set forth.

4. The combination of a bag or bottle-like vessel provided with a mouth, a tubular metallic fitting secured in the mouth of said vessel and provided with a seat for a stopper, a stopper fitted to said seat for closing the opening therein, a set of projections or supports formed on the said fitting, a yoke removably secured to said projections or supports, a set screw having a threaded bearing in said yoke and having its lower end connected with said stopper, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto set my hand in the presence of the two subscribing Witnesses.

JOHN NUTTALL.
